Without giving any detailed information, Madfinger Games announced that because the piracy rates of their game Dead Trigger were so high on Android, they made the game available for free. This sucks balls. I'm interested in more detailed statistics, especially where, exactly, the piracy rate is highest, considering you can only get paid Google Play applications in 31 countries, and then, often only with a credit card (which many people outside of the US don't have and/or use). It wouldn't surprise me in the slightest if those piracy rates mostly come from places without paid applications support and/or with lousy payment options. In any case, Google needs to get its act together with the Play Store.

It depends on the bank. Banks choose to enable internet transactions or not. Too many want the security of a CC, before they allow you to pay online.

I'm telling you now that nearly all UK debit cards work online. And its been like this since as long as I can remember. Even my old Solo account worked on most sites that only officially supported Mastercard, and that was nearly 15 years ago.
